IMPROVEMENT IN SPINNING-SPINDLES AND THEIR SUPPORTS.

Specification forming part of Letters Patent No. 214,750, dated April29, 1879 application filed December 24, 1878.

To all whom it may concern:

Be it known that I, JOHN BIRKENHEAD, of Mansfield, of the county ofBristol and State of Massachusetts, have in vented a new and usefulImprovement in Spinning- Spindles and their Supports; and do herebydeclare the same to be described in the following specification, andrepresented in the accompanying drawings, of which- Figures 1 and 2 arefront elevations, and Figs. 3 and 4 are vertical sections, of twospindles and their appurtenances provided with my invention. Fig. 5 isan elevation of a combined step and bolster, to be hereinafterdescribed, it having oblique channels or grooves cut in it.

The nature of my invention is fully set forth in the claim or claimshereinafter made. i

In the said drawings, A denotes a spinningframe spindle arranged withina combined step and bolster, B, which has formed in it above its step aa series of helical or inclined slits or grooves, b, which extend fromthe step up to the spindle bearing c of the bolster d. Within the saidbolster, and near its top, the spindle has a groove, e, madetransversely in and around it, such groove being to prevent oil fromflowing out of the top of the bolster down upon the outside of thecombined step and bolster supporter G, into which the combined step andbolster B is fitted, and below which it extends, in manner asrepresented. This supporter O is a tubular standard provided with abroad cylindrical base, f, having upon its upper surface or part anannular trough, d, such trough being arranged concentrically with thestandard and base and furnished with an educt or passage, h, leadingfrom it into the space within the.aforesaid part B.

There is to the base f a flange, i, which extends down from it, asshown, and encompasses the upper part of a socketed and tenoned pedestal, D, arranged beneath the supporter O, and fixed, as shown, to restupon and enter what is termed the spindle-sustaining rail, the tenon ofthe pedestal to enter the said rail being shown at a.

Between the bottom of the supporter G and the top of the pedestal is ayielding disk or annulus, E, of cloth, leather, or other suitablematerial.

In Fig. 3 the supporter G is represented as fixed to the pedestal byscrews 1 l, going down through the base of the supporter and alsothrough the yielding disk or annulus, the coinbined step and bolsterbeing extended below the latter and into a recess or chamber, m, made inthe pedestal, and having a diameter somewhat larger than that of thepart within it.

In Fig. 4 the cavity min the pedestal is represented as provided with afemale screw, 0, formed down within it to receive a male screw, 1), ofless diameter, made on the part of the combined bolster and step thatenters the said cavity. The male screw is to work loosely laterally inthe female screw, in order to enable the spindle and its combined stepand bolster and the supporter thereof to vibrate or play laterally, theyielding annulus E admitting of such movements. The screws 0 p serve tohold the part B in connection with the pedestal. To prevent the standardfrom revolving on such pedestal a screw, 8, is inserted in the latterand projects into a notch, 25, made in the flange of the supporter.

Furthermore, the whirl u is fixed to or makes part of a conical cap orcover, H, which, fastened on the spindle, projects down around thestandard, and at bottom has a groove, o, out in and around it to receivea stud, w, extending from the standard. The groove has a passage, ac,leading downward out of it, as shown in Fig. 4., and also in Fig. 6, thelatter figure being a bottom view of the cap H. Fig. 7 is a sideelevation of the standard and its base, showing the notch t in thelatter to receive the screw 8.

The cushion or annulus E, applied as described, will yield to allow thespindle while revolving at great velocity to adjust itself into avertical position.

By arranging the groove 1; and its outlet .4: in the cap and theengaging-stud win the standard, I save the necessity of making thestandard with an extension to enter the oil-reservoir and to have thestud projecting from it (the said extension) and under a flange arrangedat the top of the said reservoir, as shown in the United States Patent N0. 205,718.

The oil that passes from the trough into the part B will, by the actionof the spindle while revolving and the inclined grooves or helical slotsin such part B, be raised up to the hearing in the upper portion ofthesaid part B, the surplus being materially prevented by the groove in thespindle from overflowing and passing down on the outer surface of thestandard.

It is not new, as will appear by Patent No. 157,437, to have a groove inand around the spindle when the spindle is within a combined step andbolster; but in such case the groove was placed considerably below, andnot at the top, of the bolster, as shown in the accompanying drawings.In my present arrangement the groove operates to better advantage tostop or diminish the overflow of the oil.

The small amount of oil that will escape and run down the outer surfaceof the standard and the inner surface of the cap will sutfice to keepthe rubbing-surfaces of the stud w and the groove awell lubricated.

In the present arrangement of the stud and groove there is a practicaladvantage over what of like character is shown in the afore said PatentNo. 205,718, in which, owing to the stud beingxvholly above any oil inthe reservoir, it is often difficult to keep the stud well oiled andfrom Wearing and being worn by the flange with which it co-operates.

With my present arrangement of the stud w and the groove o they are keptthoroughly lubricated by the small amount of oil that escapes and runsdown on and between the standard and the cap.

I claim as my invention as follows:

1. The spindle provided with the groove 0,

arranged at the top of the bolster, in combination with the combinedstep and bolster B, having the oil raising helical grooves or slots 1),and with standard 0 and cap H, arranged as set forth.

2. The cap H, provided with the groove o and its outlet 00, and fixed tothe spindle and arranged wholly above the oil-receiver, in combinationwith the spindle and with the standard G, furnished with the stud w toengage with such groove, as explained.

3. The combination of the spindle A, the cap H, having whirl a, thestandard (3, provided with the oil-trough d, and its educt h, thecombined spindle step and bolster B, yielding annulus E, and thepedestal D, all arranged and applied substantially as set forth.

4. The combination of the spindle, cap, and whirl, and the standardprovided with the oilreservoir and its educt, and the yielding annulusor cushion, and the tenoned pedestal, all

arranged and applied substantially as specified.

5. The combination of the chambered pedestal D, yielding annulus E,standard 0, having the base f, trough h, and flange 1', combined stepand bolster B, fixed tightly in and pro jecting from the said supporterinto the chamber of the pedestal, and devices or mechanism for holdingthe supporter on and preventing it from revolving on such annulus, allbeing substantially as set forth.
